英文摘要：

With the development of material science and advanced manufacturing technology, difficult-to-machine materials have been widely used in many departments because of the excellent physical and mechanical properties. Pointing to the construction features of difficult-to-machine materials, the machining performance of difficult-to-machine material is discussed. A comprehensive review on the research progresses of hard cutting, ultrasonic assisted machining, laser heat as- sisted machining and hot ultrasonically assisted machining for difficult-to-machine materials at home and abroad is presen- ted. Some problems and the advanced research prospect in this aspect is made.
